[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] In traditional concrete construction, concrete thickness is often controlled by methods such as installing positioning reinforcement bars, stringing lines, and positioning formwork. While these methods can control the thickness of the concrete structure, the measuring equipment cannot be reused, and the measurement location is limited.
[0034] In view of this, such as Figures 1-9 As shown, some embodiments of this utility model provide a concrete pouring thickness measuring device, including a probe cone 1, a contact disc 2, a scale column 3, and a sleeve 4; one end of the probe cone 1 is connected to the scale column 3, and the other end of the probe cone 1 is provided with a pointed part, which extends into the concrete 5 and abuts against the bottom of the concrete 5; the scale column 3 and the sleeve 4 are slidably connected, and the scale column 3 drives the probe cone 1 to slide relative to the sleeve 4; the contact disc 2 is provided on the side of the sleeve 4 close to the concrete 5, the contact disc 2 is connected to the sleeve 4, the contact disc 2 is grounded on the concrete 5, and a through hole is provided on the contact disc 2, through which both the probe cone 1 and the scale column 3 can extend.
[0035] In the above embodiments, the probe cone 1, the abutting disc 2, the scale post 3, and the sleeve 4 can all be made of metal. The probe cone 1 can be conical, with a pointed end at one end and a circular end at the other. The circular end of the probe cone 1 can be provided with a threaded post. The scale post 3 can be cylindrical, with a threaded hole at one end. The probe cone 1 can be threadedly connected to the scale post 3. The sleeve 4 can also be cylindrical, hollow inside, and its inner wall can be spaced apart from the outer walls of the probe cone 1 and the scale post 3, thereby allowing the probe cone 1 and the scale post 3 to slide relative to the sleeve 4. The abutting disc 2 can be annular, and a through hole can be provided at the center of the abutting disc 2. The through hole can also be circular, so that the scale column 3 and the probe cone 1 can pass through the through hole. The abutting disc 2 can be welded to one end of the sleeve 4. By attaching the abutting disc 2 to the surface of the concrete 5, the scale column 3 is pushed so that the probe cone 1 abuts against the bottom of the concrete 5 layer. At this time, the side of the scale column 3 away from the concrete 5 extends out through the sleeve 4. At this time, the vertical distance between the tip and the surface of the abutting disc 2 is the same as the length of the scale column 3 extending out. Thus, the thickness of the concrete 5 can be judged by the length of the scale column 3 extending out.
[0036] This utility model provides a concrete pouring thickness measuring device, comprising a probe cone 1, a contact disc 2, a scale column 3, and a sleeve 4. One end of the probe cone 1 is connected to the scale column 3, and the other end of the probe cone 1 is provided with a pointed end that extends into the concrete 5 and abuts against the bottom of the concrete 5. The scale column 3 and the sleeve 4 are slidably connected, and the scale column 3 drives the probe cone 1 to slide relative to the sleeve 4. The contact disc 2 is located on the side of the sleeve 4 near the concrete 5 and is connected to the sleeve 4. The contact disc 2 is grounded on the concrete 5 and has a through hole. Both the probe cone 1 and the scale column 3 can extend from the through hole. The probe cone 1 abuts against the bottom of the concrete 5, and the contact disc 2 abuts against the surface of the concrete 5. The scale is observed by using the connected scale column 3 in conjunction with the sleeve 4. This device solves the technical problems of existing measuring devices being unreusable and having a single measurement position, achieving the technical effect of reusable measuring devices, measuring multiple positions, and providing more comprehensive measurements.
[0037] In an optional embodiment, an extension rod 6 is also included, with one end of the extension rod 6 connected to the probe cone 1 and the other end of the extension rod 6 connected to the scale post 3, so that the extension rod 6 can extend through the through hole.
[0038] In the above embodiment, the extension rod 6 can be cylindrical, made of metal, with a threaded post at one end and a threaded hole at the other end. The threaded hole of the extension rod 6 can be threadedly connected to the probe cone 1, and the other end of the extension rod 6 can be connected to the scale post 3, so that it can be used to deal with concrete 5 of different depths. Therefore, when dealing with concrete 5 of different depths, the extension rod 6 of appropriate length can be selected.
[0039] In an optional embodiment, the axes of the sleeve 4, the scale post 3, the probe cone 1, and the extension rod 6 are aligned.
[0040] In the above embodiment, the sleeve 4 is cylindrical, the scale post 3 and the extension rod 6 are both cylindrical, the probe cone 1 is cylindrical, and the axes of the sleeve 4, scale post 3, probe cone 1 and extension rod 6 are aligned, which effectively reduces the volume.
[0041] In an optional embodiment, the axes of the sleeve 4, the scale column 3, the probe cone 1, and the extension rod 6 are all aligned with the thickness direction of the concrete 5.
[0042] In the above embodiment, the abutting disc 2 can be set perpendicular to the axis of the sleeve 4, and the abutting disc 2 can abut against the surface of the concrete 5. The axes of the scale column 3 and the probe cone 1 can both extend vertically into the concrete 5, and the thickness of the concrete 5 can be effectively measured through the scale column 3.
[0043] In an optional embodiment, an elastic element 7 is also included. The elastic element 7 is sleeved on the scale post 3. One end of the elastic element 7 abuts against the probe cone 1, and the other end of the elastic element 7 abuts against the sleeve 4. The elastic element 7 has a tendency to press the probe cone 1 against the concrete 5.
[0044] In the above embodiment, the elastic element 7 can be configured as a spring. The elastic element 7 is sleeved on the scale post 3 and is disposed between the scale post 3 and the sleeve 4. One end of the elastic element 7 can abut against the probe cone 1. The maximum diameter of the probe cone 1 can be larger than the diameter of the scale post 3. The elastic element 7 can abut against the probe cone 1. The other end of the elastic element 7 can be fixed to the inner wall of the sleeve 4 by welding. The elastic element 7 has a tendency to extend the probe cone 1 into the concrete 5, thereby effectively extending the probe cone 1 into the bottom layer of the concrete 5.
[0045] In an optional embodiment, a first baffle 8 and a second baffle 9 are also included. The first baffle 8 is disposed on the side of the scale column 3 close to the concrete 5, and the second baffle 9 is disposed on the side of the scale column 3 away from the concrete 5. The first baffle 8 is connected to the scale column 3 and the probe cone 1 respectively, and the second baffle 9 is fixed on the inner wall of the sleeve 4.
[0046] In the above embodiments, both the first baffle 8 and the second baffle 9 can be annular. The first baffle 8 and the second baffle 9 are parallel and spaced apart. The first baffle 8 and the second baffle 9 are respectively disposed on both sides of the sleeve 4. The first baffle 8 is disposed close to the concrete 5, and the second baffle 9 is disposed away from the concrete 5. The first baffle 8 is connected to the scale column 3 and the probe cone 1 respectively. The first baffle 8 is sleeved on the cylinder of the probe cone 1. The probe cone 1 locks the first baffle 8 onto the scale column 3. The elastic element 7 can abut against the first baffle 8, so that the elastic element 7 can push the abutting disc 2 and the probe cone 1 to slide relative to the sleeve 4. The second baffle 9 can be disposed on the side of the sleeve 4 away from the concrete 5. The second baffle 9 can be fixed to the inner wall of the sleeve 4. The circular hole in the center of the second baffle 9 can slide with the scale column 3.
[0047] In an optional embodiment, a first retaining ring 10 and a second retaining ring 11 are also included; the first retaining ring 10 is disposed on the side of the first baffle 8 close to the concrete 5, and the second baffle 9 is disposed on the side of the second baffle 9 away from the concrete 5. The first retaining ring 10 and the second retaining ring 11 are respectively fixed on the inner wall of the sleeve 4. The first retaining ring 10 is used to abut against the first baffle 8, and the second retaining ring 11 is used to abut against the second baffle 9.
[0048] In the above embodiments, both the first retaining ring 10 and the second retaining ring 11 are annular in shape. Both are welded to the inner wall of the sleeve 4. The first retaining ring 10 and the second retaining ring 11 are spaced apart and parallel to each other. The inner diameters of the first retaining ring 10 and the second retaining ring 11 are the same and smaller than the outer diameters of the first baffle 8 and the second baffle 9. This allows the first retaining ring 10 and the second retaining ring 11 to limit the movement distance of the first baffle 8 and the second baffle 9. Specifically, when the first retaining ring 10 and the second retaining ring 11 move away from each other, the first baffle 8 and the second retaining ring 9... Plates 9 are all positioned between the first retaining ring 10 and the second retaining ring 11. When the scale column 3 moves, after the scale column 3 penetrates the concrete 5, the elastic element 7 can be compressed, the first baffle 8 separates from the first retaining ring 10, and the first baffle 8 can move close to the second baffle 9, so that the scale column 3 extends out through the second baffle 9. After the measurement is completed, the probe cone 1 extends out of the concrete 5, and the elastic element 7 pushes the first baffle 8 towards the first retaining ring 10, so that the first baffle 8 abuts against the first retaining ring 10, completing the reset of the probe cone 1, so as not to affect the next use.
[0049] In an optional embodiment, the inner diameter of the first baffle 8 is larger than the diameter of the probe cone 1, and the inner diameter of the first baffle 8 is larger than the diameter of the scale post 3, and the inner diameter of the second baffle 9 is larger than the diameter of the scale post 3, so that the probe cone 1 can drive the first baffle 8 and the scale post 3 to move relative to the sleeve 4.
[0050] In the above embodiment, in order to block the first retaining ring 10 and the second retaining ring 11, and to allow the probe cone 1 to extend into the first retaining ring 10 and the first baffle 8, the inner diameter of the first baffle 8 is larger than the diameter of the probe cone 1 and the scale post 3, and the inner diameter of the second baffle 9 is only larger than the diameter of the scale post 3. Thus, the probe cone 1 can drive the first baffle 8 and the scale post 3 to move, and the first baffle 8 can abut against the first retaining ring 10.
[0051] In an optional embodiment, the scale post 3 is provided with marking scales that extend along the length of the scale post 3.
[0052] In the above embodiment, the marking scale can be in the shape of a strip. The marking scale is set on the surface of the scale column 3. The 0 mark of the marking scale can be set close to the concrete 5 and extend away from the concrete 5. When the tip is flush with the abutting disc 2, the length of the scale column 3 extending out of the sleeve 4 is the longest. At this time, the 0 mark line of the marking scale on the sleeve 4 is also aligned with the sleeve 4, and the thickness measured at this time is 0.
[0053] In an optional embodiment, a hand-held part 12 is also included; the hand-held part 12 is sleeved on the sleeve 4, the hand-held part 12 is located on the side of the sleeve 4 away from the concrete 5, and the hand-held part 12 is connected to the sleeve 4.
[0054] In the above embodiments, the handheld part 12 may be made of metal. The handheld part 12 may include a ring and a handle. The ring and the handle may be welded together. The ring may be threaded onto the sleeve 4, and the handle may be spaced apart from the end face of the sleeve 4, thereby providing space for the movement of the scale column 3.
[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
